The crystalline lens is a biconvex, transparent structure, located
behind the pupil that focuses light onto the retina. It has the ability
to change its shape, and therefore make finer adjustments to focus
the image perceived. With time, the lens becomes rigid and
increases in size. Therefore, focusing on near objects tends to
become increasingly difficult as the person approaches the range
of 45-50 years. This phenomenon is known as “presbyopia”.
When the lens becomes cloudy or opaque, it is named “cataract”.
To model this part, we used 3ds Max. This tool allowed us to
create a model of the crystalline lens that can be easily modified
to create a custom lens with some required features.
